Validator overview

The relative volume Validator calculates the time difference on two rows for each record:

Count ratio: Calculates the ratio between the number of rows in the source and the number of rows in the reference source.
Percentage ratio: Calculates the ratio between the percentage of rows in the source and the percentage of rows in the reference source that pass a given Filter criteria.

Reference source

For information on how you configure the reference source, refer to reference source.

Sensitivity

Higher sensitivity means that the accepted range of values is narrower, which identifies more anomalies. Conversely, lower sensitivity values imply a wider range of accepted values, which identifies fewer anomalies.
